Horizen was launched in May 2017 as an interoperable blockchain ecosystem that fosters real-world use cases. A vast and globally distributed infrastructure of over 40,000 decentralized nodes supports the network, alongside features like a PoW mainchain, PoS sidechains, zk-SNARKs, TLS end-to-end encryption, and 51% attack resistance. Zendoo, ZenNodes, Sphere, Horizen Development Environment (HDE), Horizen Community Council (HCC), and the Horizen Academy are some of Horizen’s coveted community-oriented solutions. The project ensures optimum user participation through the Horizen Improvement Proposal System (ZenIP), which is a cornerstone to the platform’s collaborative environment. Responsible Privacy — Horizen’s proprietary solution — enables users to fully control their privacy and data sharing terms. ZEN is Horizen’s native, PoW-based, mineable cryptocurrency, with a maximum supply of 21 million.
